To (6 whom 2'25 may concern; 7

Be it known that I, ALBERT T. LOFTSGAAR- DEN, of the city of Powell, inthe county of Park and State of WVyoming, have invented certain new anduseful Improvements in Haystackers of which the following is aspecification.

This invention relates to improvements in hay stackers and the primaryobject of the invention is to furnish a hay stacker embodying a combinedoscillating and slidable elevator, designed to receive hay while inhorizontal position and then to be swung about its fulcrum and extendedto elevate the load. 5

Another object of the invention is to furnish a, device of thischaracter with improved means forming an extension for the base of theapparatus so that the device may be used on rough hard ground withoutdriving stakes or the like to anchor the apparatus.

A further object of the invention is to furnish a. device of the typeindicated with improved means for simultaneously swinging the elevatingmechanism about a horizontal axis and extending the samelongitudinally'. The apparatus includes means for swinging the elevatorframe without extending the elevator, and it also includes means forsimultaneously carrying out these operations.

With the foregoing objects outlined, and with other objects in viewwhich will appear as the description proceeds the invention consists inthe novel features hereinafter described in detail. illustrated in theaccompanying drawings and more particularly pointed out in the appendedclaims.

Referring to the drawings:

Figure .1. is a perspective view of my improved apparatus showing theelevator frame raised and the elevator itself in lowered position.

ig. 6 is a detail perspective view of the upper end of the elevatorframe and show:

ing certain ropes connected to the same;

Fig.7 1s a perspective view of one of the blocks forming the extensionfor the apparatiis base. r

In the drawings, 1 designates a base designed to rest in horizontalposition on the ground upon which the apparatus is erected and includingside bars 1 and 1? having their ends connected together by bars 1 1 Thebase is braced by means ofa'V-shaped bracket 1 which has its centralportion secured to the bar 1 and its ends extended through the side barsof the base as shown at 1 to provide pivot pins for the elevator framewhich will be hereinafter described.

In order to prevent the apparatus from toppling over when the elevatorframe is raised into substantially vertical position, I provide a baseextension consisting of blocks 2 which extend beyond one end of theframe and are provided with latching members 2- and 2 The members 2engage the front ends of the bars 1 and 1 and the members 2 rest on theupper surfaces.

of the side bars of the base. With the use of this extensioii, the baseof the apparatus will be prevented from toppling over and it will not benecessary to employ stakes or other anchoring means, which must bedriven into the soil.

3 designates the elevator-frame which is provided at its lower end withfulcrum blocks 3* that are pivotally connected to the pins 1". Thisconnection permits the frame 3 to be placed in a position parallel withthe base 1 or to be moved into a position substantially perpendicular tothe base. vThe elevator frame includes pairs of side bars 3*, 3 and eachpair of these bars have their lower ends secured to the fulcrum blocks 3and are spaced apart throughout substantiallv their entire length toprovide elevator guides3 The upper ends ofthe bars of each pair 3 and 3are spaced apart and connected together by rectangular collars 3". Theupper ends of the bars 3 are secured together by a cross bar 3 and theupper ends of the bars 3 are connected together bv the cross bar 3together and braced by means of a cross bar 3. Thebars 3 3273 3 and 3form a substantially rectangularelevator frame and this frame is bracedby means of a The lower ends of the, side bars of the elevator frame areconnected V-shaped bracket 3 which has its central portion secured tothe bar 3 andits ends connected to the bars 3 n The elevator framesupports an elevator 4:

consisting of a head 4? and side bars 4 The side bars are slidablymounted in the guides 23 and they are provided at their lower ends withplates 4; which are secured to the elevator side bars on opposite sidesof the bars 3 and 8 and slidably engage the last mentioned bars. It willthus be seen that the elevator may be extended relatively to theelevator frame 3 and the side bars d slide through the collars 3 at theupper ends of the side bars of the elevator frame 3.

The mechanism for swinging the elevator and elevator framefromhorizontal position to a substantially vertical position and forextending the elevator relatively to the elevator'frame, includes aderrick 5 which lS Of V shape and consistsof side bars 5 having theirlower ends pivotally connected at 5 to the side bars of the base 1.

nected to a head5 and by viewing the drawings .itmay be seen that thederrick 5 may be swung from theposition shown in Fig. 3 to the positionsshown in F igs. 1

and 4.

One of the means for swinging the derrick from one pos tion to another'COIlSlSlZS of a ropeor cable 6 having one of its ends secured to apulley 6 which is connected to the head 59; The rope 6 is extended fromthe pulley 6 through a pulley 6 carried by the endbar 1 of the base andfrom the pulley6 it is passed around the sheaf of the pulleyb and isthen returned over the sheaf of -jth'e pulley 6 and extended out wardly,and its end 6 .is designed to be secured to the single tree 11? or otherdrawing inechanism for the purpose of lJGDSlODlHg the rope 6 and causingthe bar 5 of the derrick to be swung toward the bar 1.. The headof thederrick is'connected by cables 7 to the upper or outer end of theelevator frame 3 and it. will be seen that the ropes as best shown inFig. at. The lower end of the rope 8 is "connected to one end of ftCOllspring 8 the otherend of the spring be mg secured to the cross-bar 1;and the spring functioning to aid in returning the elevator frame to itshorizontal position. From theforegoing it wlll. be understood thatwhenthe elevator is in horizontal position as shown in Fig. 3, hay. or thelike may be placed on the elevator head 4: and then by drawing onitherope 6 the pulley 6 will be drawn towards the pulley 6 and this frameand elevator without causing the The upperforouter ends of the side bars5 are conwill cause the derrick to swing on its pivots 5 and the ropes 7to swing the elevator frame on its pivots i This mechanism abovedescribed will swing the elevator elevator t to be extended and this isdesirable in cases where the load is to be raised only short distances.

In order, however, to cause the elevator to be extended simultaneouslywith the swinging of the elevator frame 3 on its pivotsI have providedthe following mechanism. Ropes or cables 9 have ends connected.

to the derrick at the point 9* and these ropes pass over pulleys 9 fixedto the lower end of the elevator frame. From the pulleys 9 the ropesextend to 'screw'eyes or the like 9 fixed to the. lower ends of the sidebars 4:? of the elevator. The ends of the ropes 9; are "tied or securedto the screw eyes 9 Extending from the screw eyes ,9 are other ropes 10which pass over pulleys 1O fixed to the side bars 3 of the elevatorframe and have their ends connected to a pulley 1O which they support.From Fig. 1 it may be seen that drawing downwardly the pulley 10 willcause the ropes 10 to move the elevator outwardly relatively to theelevator framed and as the elevator moves outwardlythe screw eyes 9 willmove away fromthe pulleys 9 and cause the derrick 5 tobe swung on itspivots. The means for operatingthe pulley 10 consists of a rope 11having one of its ends fixed to a pullley 11 carried by the crossbar 1of the base. The rope fl 1, passes from the pulley 1.1 around the sheafto the pulley 1O then back through the pulley 11 and is provided at itsother end with a chain 11 the links of which are designed to be engagedby a hook 11 formed on the single tree 11 By adjusting the single treehook from the links of the chain 11*" the height to which the elevatorwill he raised may be adjusted.

From this description it will be understood.

that the ropes 6 and fll maybe simultaneously secured to the single treefor the purposeof actuating these ropes and the mechanisms ,to whichthey are connected, at one time. It is obvious that either one of theropes maybe tensioned without the tensioning of the other rope whendesired.

Attention is called to the fact that when thefelevator frame 3 is swungfrom the position shown in Figure 1 to the position shown in Figure 3,the cables 7 will raise the head 5? of the derrick and this will causetheropes 9 to draw the side bars 4* of the elevator into the frame 3. Inother words, the movement of the elevator frame from "substantiallyvertical to horizontal position, causes the ropes 9 to return theelevator 4: to its normal position.

I believe from the foregoing description that the construction andoperation of my apparatus will be apparent to those skilled in the art,and I am aware that various changes and modifications may be made in theconstruction illustrated without depart ing from the spirit of theinvention or sacrificing any of its advantages.
